AJM, I had the same issue with blootube-wide (but not
bluetubelite-wide), what would happen is myfrontend would quickly eat
up all available memory trying to go to the mytharchive menu,
(including swap, ~2Gb!) It's fixed now in SVN, I believe it was
Changeset 13513 that did it, and I think this has been backported to
0.20-fixes.
